Commercial poultry feed accounts for 60% to 70% of total production costs for livestock farmers across Sarawak, driven by heavy reliance on imported corn and soybean meal. Utilizing locally sourced agricultural by-products like Palm Kernel Cake (PKC) combined with high-value bio-proteins—such as Black Soldier Fly Larvae (BSFL)—allows farmers to cut feed overhead by 20% to 35% without sacrificing flock growth rates.
Understanding PKC and Bio-Protein Performance
- Palm Kernel Cake (PKC): A abundant by-product from Sarawak’s palm oil mills containing 14–16% crude protein and high energy content. Because raw PKC contains high fiber (15–18%) and mannan polysaccharides, pre-treating or fermenting it boosts digestibility for poultry.
- Bio-Protein (BSFL): Black Soldier Fly Larvae reared on organic market waste yield 40–45% crude protein and 30% healthy lipids. BSFL serves as a direct, locally produced alternative to expensive imported fishmeal and soybean meal.
Recommended Feed Inclusion Rates
Incorporating alternative ingredients requires balanced substitution ratios based on the digestive sensitivity of each poultry class.
| Poultry Type | Max PKC Inclusion Rate | Max Bio-Protein (BSFL) Inclusion Rate | Primary Nutritional Benefit |
| Ayam Kampung / Free-Range | 20% – 30% (Fermented) | 10% – 15% (Fresh or Dried) | High fiber tolerance, strong natural foraging intake |
| Layer Hens (Egg Production) | 10% – 15% (Solid-State) | 8% – 10% (Dried Meal) | Maintains egg weight and improves shell thickness via natural calcium |
| Broiler Chickens (Finisher Phase) | 10% – 15% (Max) | 5% – 8% (Dried Meal) | Sustains rapid daily weight gain without gut irritation |
2-Step Method to Optimize Raw PKC for Chickens
- Solid-State Fermentation: Mix raw PKC with water (60% moisture) and an Effective Microorganism (EM) or fungal starter culture (Aspergillus niger or yeast). Seal in airtight barrels for 4 to 7 days. Fermentation breaks down crude fiber and boosts available protein by 4–6%.
- Drying and Storage: Sun-dry the fermented PKC to below 12% moisture content before batch mixing to prevent mold growth (Aflatoxin contamination) during storage in humid Sarawak environments.
Best Practices for On-Farm Feed Blending
- Balance Amino Acids: PKC is naturally low in lysine and methionine. Combine PKC with BSFL or synthetic amino acid supplements to prevent growth stunting.
- Gradual Transition: Introduce alternative feed mixtures over a 10-day transition period (25% new feed on days 1–3, 50% on days 4–7, 100% by day 10) to avoid digestive stress in your flock.
